  • Several studies have demonstrated that ginseng-berry extract has several beneficial properties, including anti-inflammatory, antioxidant, and vasodilation properties. Ginseng-berry extract has also been shown to have the great potential against skin aging. Its beneficial mechanism against skin aging, however, has not been examined in detail. Also, the effects of ginseng-berry extract on microcirculation and skin cellular responses have not been investigated. Inhibition of skin microcirculation is the primary cause of many adverse biological effects, which is responsible for the skin aging and darkening. We investigated the beneficial effects of ginseng-berry extract on blood circulation, transcutaneous oxygen pressure in vivo model and also on skin microcirculation, cellular response and skin brightening effect in clinical trial. We found that oral administration of ginseng-berry extract markedly increased blood flow rate and transcutaneous $O_2$ pressure, but decreased transcutaneous $CO_2$ pressure. Also, it improved skin tone on cheeks, as is skin brighteness. These results suggest that ginseng-berry extract is a potent candidate for the treatment of skin aging and brightening by improving skin microcirculation.

  • The cutaneous microcirculation plays a role in various physiological processes and pathological conditions. Two non-invasive methods were used in this study to obtain reference values for cutaneous microcirculation in intact male beagles. Twenty intact male beagles were used. The experimental environments were standardized. Laser Doppler flowmetry was used to measure cutaneous blood flow, and an infrared thermometer was used to measure cutaneous temperature. The blood flow and temperature were measured from the right side of the subjects at 20 cutaneous sites. Based on the laser Doppler flowmetry, the region with the highest blood flow was the periocular region that with the lowest was the forelimb foot pad. In addition, the standard deviation of the chest wall was the highest while that of the periocular region was the lowest. For skin temperature, the inguinal region had the highest mean skin temperature and the forelimb foot pad had the lowest. The correlation coefficient between the two methods was 0.72. Similar to a previous study, the values derived from repeated measurements at the 20 regions are reproducible and can contribute to research. Compared to the results of a previous study, the temperatures of the two smallest skin regions were the same; however, no specific trend was observed. The correlation coefficient between the two methods was significantly comparable, and this good correlation can reduce their limitations and variables complementarily. In addition to possible use in human studies, accumulated resources on measurements of skin blood flow in the future will potentiate its use in the veterinary medicine field.

  • Recently prostaglandin $E_1(PGE_1)$ has been shown to ensure flap survival by producing vasodilation of the peripheral vessels and platelet disaggreation. However, direct observation and detailed quantitative studies of the effects of $PGE_1$ on the cutaneous microcirculation have not been reported. In the present study, we investigated cutaneous microcirculatory changes in the rabbit ear chamber(REC) with an intravital microscope following intravenous administration of $PGE_1$. The results obtained in this study indicate that $PGE_1$ administered intravenously at a rate of 200ng/kg/min might act directly on the vessels and cause dilatation of metarterioles and capillaries without affecting vasomotion and systemic blood pressure. Clinically in order to evaluate the effect of an intravenous administration of $PGE_1$ on the cutaneous microcirculation, cutaneous blood flow, skin temperature and transcutaneous $Po_2$ in the pedicle or free flap of operated patients were evaluated by the combination of several measurements following the administration of $PGE_1$. The present study suggests that improvement of cutaneous microcirculation by $PGE_1$ may enhance the survival rate of flap or replantation. Both vessel arterial ischemia and venous congestion are main factors of tissue necrosis in the flap surgery. Vasodilatory or antithrombotic agents have been used in salvage of flap necrosis. However, the therapeutic effects of those drugs are still not well elucidated. Recently prostaglandin $E_1(PGE_1)$ has been shown to ensure flap survival by producing vasodilatation of the peripheral vessels and platelet disaggregation[1-3]. Emerson and sykes[4] have obtained significant improvement in the flap survival in the rat using $PGI_2$. Suzuki et al.[5] have reported prolonged flap survival length by using $PGE_1$ in the rabbit and concluded that $PGE_1$ improved the microcircuration in the flap. However, direct observation and detailed quantitative studies of the effects of $PGE_1$ on the cutaneous microcirculation have not been reported. In the present study, we investigated microcirculatory changes in the rabbit ear chamber[6,7] with an intravital microscope following intravenous administration of $PGE_1$.

  • Back ground and Objective : There is a need for objectification and scientific verification of Pattern identification in Oriental medicine. The purpose of this study was to investigate the skin characteristics of Qi deficiency and Blood deficiency animal models. Material and Methods : Sprague-Dawley rats were divided into three groups: normal group, Qi deficiency group and Blood deficiency group. The Qi deficiency animal model was induced through restriction of food (75g/kg/day) for 20 days. Blood deficiency animal model was induced by bleeding from tail vein(0.3 ml/time) 8 times. The normal animal model was kept without any intervention. The general condition was observed by measuring body weight, body temperature, blood pressure, pulse rate, and hematological and biochemical parameters. The skin characteristics were observed by measuring the erythema index(EI), melanin index(Ml), transepidermal water loss(TEWL) and dermal microcirculation. Results : 1. In the Qi deficiency group, body weight was lower than the other groups. In the Qi deficiency group, blood pressure was lower than in the Normal group. There was no difference in body temperature and pulse rate between the three groups. 2. In the Qi deficiency group, blood sugar was lower than in the Blood deficiency group. There was no difference in triacylglycerol between the three groups. In the Qi deficiency group, the WBC count was lower than in the Blood deficiency group. RBC count was highest in the Qi deficiency group, Normal group and Blood deficiency group respectively. In the Qi deficiency group, Hb and Hct were higher than the other groups. 3. EI and MI were decreased in the Qi deficiency group, and EI showed a significant decrease. 4. EI and MI were increased in the Blood deficiency group, and MI showed a significant increase. 5. TEWL was significantly increased in the Qi deficiency group, while it was decreased in the Blood deficiency group, TEWL was highest in the Qi deficiency group, Normal group and Blood deficiency group respectively and all three groups showed significant difference. 6. In the Qi deficiency group, dermal microcirculation was lower than the other groups. Conclusion : The above results show that the erythema index decreases in the Qi deficiency model, and the melanin index increases in the Blood deficiency model. The Qi deficiency animal model shows an increase in transepidermal water loss, while the Blood deficiency animal model shows a decrease. Further studies should develop new models of Pattern Identification that are more specific.

  • Cosmetic mask is one of the traditional cosmetic product and is used to keep skin healthy and beautiful through moisturizing effect, cleansing effect and acceleration effect on microcirculation. There are several types of cosmetic mask such as peel-off type, tissue-off type, wash-off type and cotton sheet type immersed in cosmetic water. It is important for cosmetic formulators to develop an adequate type of cosmetic mask that meets the needs of the target consumers because each type of cosmetic mask has benefits and problems in its usage and efficacy. Polyvinyl alcohol (PVA) is widely used as an active ingredient of peel-off type cosmetic mask and the physical property of the PVA film changes with the usage of other ingredients. We studied the change of physical properties of the film containing PVA by formulating peel-off type cosmetic mask with the variation of humectants. Methylguceth-20 and glycereth-26 reduce the interaction between skin surface and PVA film without serious weakening of tensile strength and they can alleviate irritation. Glycerin, urea and betaine help PVA film soften and they also have excellent efficacy as humectants.

  • Objective : This study was conducted to offer basic materials for the clinical study of Chi acupuncture (carboxytherapy). Methods : Recent clinical studies were reviewed for carboxytherapy (carbon dioxide therapy) and the ancient and present texts were reviewed for Chi acupuncture. Results and Conclusions : Chi acupuncture is oriental medical therapeutic treatment using carboxytherapy. Chi acupuncture refers to the transcutaneous administration of CO2 gas for therapeutical purposes relating to obesity, cellulites, local circulation and skin irregularity. Recent studies have demonstrated the effects of this therapy on adipose tissue by showing vasomotor effects, increasing local circulation and inducing a partial increase in tcPO2. Chi acupuncture influences the microcirculation and likely has a positive effect upon the physiological oxidative lipolytic process.
